Abstract: PURPOSE:To increase the area of the electrical lead between the source region and the electrical wiring layer by forming a groove part having a taper shaped interior wall surface by selectively removing a specific source region, and forming the wiring layer coating the insulator film between layers. CONSTITUTION:A base region B is formed by selective diffusion of a second conductivity type impurity in a specific region of a first conductivity type semiconductor substrate 2 which becomes the drain region, and a source region S is formed by selective diffusion of the first conductivity type impurity inside this base region B. Further, a groove part 16 having a taper shaped interior wall is provided by cutting inside the substrate 2 from the window part formed by selective removal of the source region S of the gate oxide film 3, the gate electrode G, and the interlayer insulating film 4 which are formed by successive overlapping on the substrate 2. Further, the wiring layer 5 is formed by coating the interlayer insulating film 4 including the inside of the groove part 16. Because of this, the back gate region is drawn out in a stable manner and also the source region can be made to have a sufficient electrical connection area.

Abstract: PURPOSE:To ensure a large area deposition film by alternately repeating a process in which an a-Si layer is deposited and a process in which the a-Si layer is irradiated with hydrogen plasma to yield a deposition layer with 10Angstrom  or more thickness, and keeping a substrate temperature upon irradiation with the hydrogen plasma at transition temperature Tt or higher of a change in hydrogen concentration in the film. CONSTITUTION:Cleaned glass is entered into a substrate insertion chamber 903 which chamber is drawn into a vacuum, and the substrate is heated to 150 deg.C by a substrate heater 916 and is entered into a Cr sputtering chamber 900. Ar from an Ar bomb 948 is allowed to flow by opening a valve, whereby Cr is deposited on the substrate 705 by sputtering at predetermined pressure. Then, the substrate is carried into a film formation chamber 901 for film formation at 0.1 Torr pressure and with 20W electric discharge power. SiH4 gas is supplied from a bomb 950 and H2 gas from 949. An about 6000(1) a-Si film is deposited on the Cr by repeating predetermined steps 200 times, and the mean deposited film thickness at each step is set to be 10(1). Thus, substrate temperature dependency of the film upon the a-Si film formation is reduced, so that stability of the manufacture of the a-Si device is improved together with the improvement of a large uniform area.
